Mild and Site-Selective Allylation of Enol Carbamates with Allylic Carbonates under Rhodium Catalysis

摘要

The rhodium(III)-catalyzed mild and site selective C-H allylation of enol carbamates with 4-vinyl-1,3-dioxolan-2-one and allylic carbonates affords allylic alcohols and terminal allylated products, respectively. The assistance of the carbamoyl directing group provides a straightforward preparation of biologically and synthetically important allylated enol carbamates.
